12. Atletico Madrid

Fresh off of their victory in the Madrid derby this weekend, Atletico Madrid took down Porto in an Iberian derby in Portugal on Tuesday.

After marching to the locker room facing a one-goal deficit, the Spanish side turned things around in the second half as both Diego Godin and Arda Turan scored to ensure that Los Rojiblancos left the Estadio do Dragao with a three-point lead in Group G.

4. Barcelona

Barcelona evaded a second consecutive Champions League defeat at Celtic Park with a 1-0 victory over the Scottish champions.

The Catalans came to life toward the end of the second half, and they were finally rewarded for their efforts in the 76th minute with a goal from Cesc Fabregas.

Although they did take three points away from their excursion to Scotland, Barca will have to play much better than they did on Tuesday to take down AC Milan in the Group H clash of the titans on October 22.
